WATER TURBINE-WHEEL.

Specification of Letters Patent.

Patented June 17, 1913.

Application filed. April 14, 1911. Serial -No. 621,010.

To all whom it may concern:

Be it known that I, ERNST H. BRAUER, a citizen of the United States,residing at Lan caster, in the county of Lancaster and State ofPennsylvania, have invented certain new and useful Improvements in\Vater Turbine- Wheels, of which the following is a specification,reference being had therein to the accompanying drawing.

This invention relates to a turbine water wheel of that class known asvertical or cylindrical turbines which are mostly employed for highheads of water, but which may, with slight modification, be used witheither high or low pressure.

The object of the invention is to provide a wheel of this class soconstructed that it will utilize the entire force of the water. Anotherobject of the invention being to provide a wheel of novel form wherebythere is no leakage, or loss of power, and no back pressure caused bythe water not leaving the wheel freely.

Still another object of the invention is to provide mechanism fordirecting the water toward the vanes of the wheel to produce the bestresults; and also means for controlling the water feed.

The device may be used in connection with pulleys, gears or othermechanism for producing power, or the outer cylinder may be employed asthe armature of an electric generator to make power direct therefrom.

\Vith these and other objects in view, my invention consists in certainconstruction and combination of parts as will hereinafter be fullydescribed and claimed in the anneved specification and illustrated inthe accompanying drawings, which form a part of this application and inwhich like figures of reference refer to corresponding parts in all ofthe views; but it is fully understood that while I have here describedmy invention as shown, that I do not confine myself to the exact design,as slight changes may be made in the construction and arrangement of theseveral parts without departing from the spirit of the invention.

In the drawings :Figure 1, is a vertical view. partly in section, of aturbine water wheel embodying my invention; the flume box or head andlower bearings being simply indicated. Fig. 2, is a top plan view of thelower gate half and water impact guide member. Fig. 3, is a top planview of the of different diameters, and having the space between theirsides filled by a series of spaced helical blades 3, which have theiredges secured to the inner and outer surfaces of said outer and innercylinders 1, and 2, respectively, and which form a series of helicalpassages at, open at the top and bottom; while the lower ends of saidblades 3, are slightly curved at 5, to better discharge the water, andat their upper ends curved upward to present an impact surface for theentering water. Said cylinders 1, and 2, are secured on a vertical shaft6, mounted in an upper bearing 7, here shown in the fiume or head box 8and mounted in the usual way, and a lower bearing 9, in the well 10.

The outer cylinder 1, is provided with an upwardly extending portion 11,which embraces and rotates around a concentric outlet passage 12, formedin the bottom of the head box 8. A ring member 13, is secured to thelower end of the concentric outlet pas sage 12, and is provided with aseries of inclined blades 1?, which form between their adjacent sidesthe chutes 16, thus forming a guide for the water so that it strikes thehelical blades 3, at an angle of about ninety degrees, thus producingthe most efficient impact; the water thus takes an approximate verticaldownward course by gravity through the passages at, exerting a pressureon the blades 3, all secured to the outer cylinder 1, the centrifugalforce will help to give the vater a downward force, and no leakage canoccur, as would be the case if the blades 3, were not attached to theouter cylinder 1.

For closing off and regulating the supply of water, there is movablymounted in the outlet passage 12, a gate 18, which is formed with aseries of openings 19, registering with the chutes 16, when in an openposition, and when in a closed position the blank portions 20, cover andclose the chutes 16, thus preventing the passage of water.

For operating the gate 18, the same is provided with a flange 21, havinga gear rack 22, mounted thereon, which is actuated by a pinion 23,suitably mounted adjacent thereto, and operated in the usual way.

Having thus described my invention what I claim as new and desire tosecure by Let ters Patent is The combination with a head-box having acentral bearing in its bottom. and a concentric outlet passage, of awell having an opening in its upper end and a bearing located therein, apair of spaced cylinders disposed. one within the other and having theirends flush, helical blades disposed between the cylinders and securedthereto, a shaft secured within the inner cylinder and mounted in saidbearings, said helical blades terminating below the upper edge of thecylinder thus producing a. channel surrounding the walls of. the outlet,a ring disposed at the lower end of said outlet, said ring havingopenings and inclined chutes leading therefrom, a gate resting upon saidring and havlng openings for the purpose set forth a lateral extensionupon the ring and engaging one wall of the outlet, a segment upon theextension and resting upon the bottom of the head-box, a pinion engagingthe segment and means to actuate it, the helical blades being curvedbackward at their opposite ends for the purpose set forth.

In testimony whereof I aiiix my signature in presence of two witnesses.
